GAS-STOVE.

To all whom it may concern:

Be it known that I, ALFRED H. HUMPHREY, a citizen of the United States, residing at New'York, New York, have invented certain new and useful Improvements in Gas Stoves, of which the following is ,a.\specifi cation.

This invention relates to improvements in gas stoves.

The main objects of this invention are:

First, to provide an improved gas stove which is highly efficient in the matter of heat radiation.

Second, to provide animproved gas stove which may be made mainly of sheet'metal and at the same time one which has a suband attractive appearance.

Tllll'd, to provide an improved gas stove which is comparatively simple and economical in structure and at the and durable.

Further objects and objects relating to dedefinitely appear from the detailed description to follow.

I accomplish the objects of my invention 7 by the -devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawing forming a part of this specificatiomin which:

Figure I is a front elevation of a struct ure embodying the features of my invenhen.

Fig. II is a vertical central transverse section on a line corresponding to line 22 of Fig. I.

Fig. III is a vertical transverse section on a line'correspondin to line 3-3 of Fig. I.

Fig. IV is a detaiI horizontal section on a line correspondin to line 4.4 of Fig. I.

Fig. V is a detail vertical section on a line correspondingto the broken line 55 of Figs. II and III, showing details of the arrangement of the burner.

Fig. VI is a detail view partially in vertical'section on a line corresponding to line IV, showing structural details. F ig. VII is a detail vertical transverse section on a line correspondin to line 77 of Fig. I. a V

same time strong construction and opportions of the side section on a of the sheet metal wallsv being indi- In the drawing similar reference char-- acters refer to similar parts throughout the several views, and the sectional views are taken'looking in the direction arrows at the ends of the section lines.-

Referring to the drawing, in the structure illustrated, I provide a body member com: prising a back wall 1 and side walls 2, formed integrally of blank for this body member is shown in Fig. XI. The angles or bending lines are indicated by dotted lines.

The side walls 2 are provided with. parallel portions 3 adjacent the back and forwardly diverging portions 4 terminating in the outturned rolls or beads of considerable diameter constituting uprights 5. The side walls are connectedby the front plate 6 having rolls or heads 7. at its. upper and lower edges, the front plate being disposed between the side walls at the rear of the u rights 5 and secured thereto by bolts 8-disposed longitudinally through the beads and through the side walls and provided with nuts 9 clamping the side walls against the ends of the front plate.

he upper edges of the side walls are inclined forwardly; The top plate 10, in the structure illustrated, is also formed of sheet metal and is conformed to suitable outline. This top plate overhangs the rear wall and walls. v

Blocks 11 are secured in the corners of sheet metal. The

of Figs. I,

a perspective view of the main and end walls are. I

of the little the body member and provided with .u'p-

side walls and projeet forwardly from the top over the upper ends of the upri hts 5. hese arms are'secured to the top y the bolts 15 and to the side walls by bolts 16,

spaced from the arms having lugs 17 through which the bolts 16 are disposed. The front ends of the arms are secured to the uprights by the bolts 18 disposed longitudinally through the corner uprights. These corner uprights are provided with top and bottom caps 19. Legs 20 conformed to harmonize with the uprights are disposed on the bottoms thereof'and secured by the bolts 18,see Fig. VI.

The rear legs 21 are preferablysheet metal stampings angled in cross section to [it the corners of the body member and riveted thereto.

lVithin the body I mount a supporting plate 22 which is preferably a casting and has a depending flange 23 at its front edge and a series of burner openings 24. The plate has a seat 25 for the fireback 26'. The radiants 27 are mounted in front of the fire back over the burner openings. burner comprising a plurality of burner tubes 28 has tips 29 alined with the burner openings 24. The burners are mounted on the depending flange by means of the screws 30.

The supporting plate has an upwardly projecting flange 31 which retains the bottoms of the radiants, their upper ends being retained by the bail-shaped rod 32 pivoted on the side walls so that it may be swung to and from engaging position, it being-capable of being swung down in front of the upper ends of the radiants, as shown in Fig. I, or upwardly to permit their ready removal, as desired. I

The fire back has flanges 33 at its ends which project forwardly. to protect the end walls 4.

The gas manifold 34 of the burner is secured to projecting cars 35 on the outer burner tubes, as shown in Fig. V. The manifold has a plurality of nozzles 36 but in alinement with the lower open ends of the burner tubes so that gas is directed to the tubes. The gas supply pipe 37 is arranged through the rear wall and connected to the IIltlIllfOlCl.

A valve 38 controls the supply pipe, the valve having a stem 39 projecting forwardly below the front plate 6 and centrally there of, as shown in Fig. I.

A. hearth plate 40 is secured at its rear edge to the supporting plate flange 23 to rest upon the front plate and is provided with a downwardly and rearwardly turned flange i1 which engages under the upper bead of the front plate.

I preferably provide a finishing and reflecting plate i2 disposed across the angle formed by the supporting plate flange and the hearth plate, its upper edge being seoured to the supporting plate and its lower edge resting on the hearth plate, as shown. in Fig. 11. This plate 42 hasa flange 23 at its upper edge which fits into the rabbet tuting a finishing member.

14 on'the supporting plate securing a good finish at. this point. The plate :2 is preferably of polished metal so that it provides a heat reflecting surface as well as consti- The upper end of the fire back is held by a retaining member 45 which fits over the upper end of the fireback and has an arm 46 with a slot 47 therein secured to the rear wall 1 by means of the bolt 48. This means of attachment provides means for adjusting the retaining member to the fireback. The rear wall preferably has a collar 49 thereon to which a ventilating pipe may be attached.

With the parts thus arranged they'may be economically produced and assembled. While many of the parts are of sheet metal the completed structure is strong and durable and attractive in appearance.

My improved gas stove is efficient in the .matter of heat radiation and quite economical in fuel consumption.

.1 have illustrated and described my improvements in one form in which I have embodied the same for the market.
